ive been on fiverr for a while and ive only made one sale. i offer digital artwork that i constantly try to sell people in person and online, but no one is buying. what am i doing wrong?
It sounds like what you're doing wrong is trying to sell what you create rather than finding out what people need/want to buy and creating that.
What research have you done into higher-profit niches, how competitive each is, who the target market for each is, etc?
